I'm planning on using the TXPOLARITY and RXPOLARITY attributes in the RIOs on a Virtex-II Pro device (via Aurora cores) to swap the function of the N and P lines in order to help improve the path of PCB tracks to an edge connector.
Has anyone used this polarity swapping capability before? Does it work OK? Are there any "undocumented features" or pitfalls that I should know about before designing the board in this way?
TIA,
Rog.
